Special Features

Bright green 3 MOA dot stands out in varied lighting and on complex backgrounds, helping you maintain a clear aiming point on steel, paper, and reactive targets.

Oversized sight window and aspherical lens deliver a wide, distortion-free sight picture that supports fast transitions and target-to-target movement.

ShockShield polymer insert helps absorb impacts and daily abuse, protecting the optic body during training, matches, and carry.

Fast-Rack textured face lets you rack the slide off belts, holsters, or barricades for one-handed manipulations and emergency reloads.

Motion activation with a timed auto-shutoff powers the dot on when the sight moves and shuts it down after inactivity to extend battery life.

Button lockout prevents accidental brightness changes during transport or high-intensity runs, keeping your preferred setting in place.

Top-mounted battery compartment allows CR2032 changes without removing the optic from the slide or rail, preserving your zero.
